CPT® Code 64755

Transection or avulsion of; vagus nerves limited to proximal stomach (selective proximal vagotomy, proximal gastric vagotomy, parietal cell vagotomy, supra- or highly selective vagotomy)

The vagus nerve, known as the tenth cranial nerve, plays a crucial role in the autonomic nervous system, influencing various bodily functions. It originates from the brainstem and extends through the neck, thorax, and abdomen, branching out to innervate multiple organs, including the stomach and upper digestive tract. In the context of CPT® Code 64755, the procedure involves the transection or avulsion of the vagus nerves that are proximal to the stomach. This surgical intervention is primarily aimed at reducing excessive acid production in the stomach, which can help prevent the formation of peptic ulcers. The procedure may be referred to by several names, including selective proximal vagotomy, proximal gastric vagotomy, parietal cell vagotomy, and supra or highly selective vagotomy. During the operation, a midline upper abdominal incision is made to provide access to the stomach and the vagus nerve. The surgeon identifies the main vagal trunks and dissects them up to the branch that leads to the biliary tree, ensuring precise transection to minimize impact on surrounding structures. This targeted approach is essential for achieving the desired therapeutic outcomes while preserving as much function as possible in the digestive system.
